Hurricane Fiona deluges Puerto Rico

A North Atlantic hurricane and a West Pacific typhoon bring major impacts on the same weekend, showing the importance of early warning systems around the globe.

September is the peak of the Atlantic and West Pacific cyclone season. This last weekend has been particularly active. Hurricane Fiona hit the American island of Puerto Rico on Sunday, September 18, pouring torrential rains and causing "considerable" damage including power outages. The cyclone notably caused landslides, brought down trees and power lines, made roads impassable and led to the collapse of a bridge in a mountainous region.

Fiona carried winds blowing up to 140 km/h. It is now off the island but torrential rains were still expected in Puerto Rico overnight, producing “life-threatening and catastrophic flooding along with mudslides and landslides” alerted the Regional Specialized Meteorological Center (RSMC) Miami Hurricane Center. Fiona is tracking over Dominican Republic, and “life-threatening flash and urban flooding” is likely to occur on the eastern part of the island.

The depression, which upgraded from a tropical storm to a Category 1 hurricane on Sunday, is expected to strengthen and become "significant within 48 hours" according to the NHC, before heading north towards the Atlantic Ocean. Fiona has already killed one person and caused significant damage during her visit to Guadeloupe, on the night of Friday to Saturday.

Powerful Typhoon Nanmadol hits Japan

Typhoon Nanmadol made landfall on Japan’s Kyushu Island on Sunday, September 18. Nine million people have been told to evacuate their homes. This powerful typhoon has killed two people and injured almost 90. Nanmadol has brought gusts of up to 234km/h (145mph), and some areas were recorded as much as 900mm (35 inches) of rain in 24 hours.

RSMC Tokyo Typhoon Centre predicted that Nanmadol would maintain typhoon strength for an additional 12 hours, when it would be more than 240 kilometers from its initial landfall location in Kyushu. Nanmadol is expected to turn to the northeast and track directly up the Japanese main island of Honshu, bringing strong winds and torrential rains to a remarkably large area of Japan

“When the Japanese Meteorological Agency (JMA) provides early warnings, local governments respond by providing people information about how to evacuate, what to bring with them, and other protection measures. Evacuation warnings are not mandatory, and authorities have in the past struggled to convince people to move to shelters before extreme weather events.”, said James Douris, WMO expert in Disaster Risk Reduction. Nine million people in Japan were told to evacuate this weekend.

“The price of fossil fuel addiction”

“Floods, droughts, heatwaves, extreme storms and wildfires are going from bad to worse, breaking records with alarming frequency. (…) There is nothing natural about the new scale of these disasters. They are the price of humanity’s fossil fuel addiction,” said UN Secretary-General António Guterres last week as we were releasing the United in Science 2022 report.

“Climate science is increasingly able to show that many of the extreme weather events that we are experiencing have become more likely and more intense due to human-induced climate change. We have seen this repeatedly this year, with tragic effect. It is more important than ever that we scale up action on early warning systems to build resilience to current and future climate risks in vulnerable communities,” said WMO Secretary-General Prof. Petteri Taalas.

Early Warnings for all Initiative presented in New York this week

“Everyone on Earth should be protected by an early warning system within the coming five years”, announced UN Secretary-General António Guterres in March 2022. The World Meteorological Organization (WMO) was requested to present a roadmap to the UN Climate Change conference, COP27, in Egypt in November. On the sidelines of the 77th General Assembly High-Level week in New York, an Early Warnings for Climate Adaptation Ministerial Event will be held on 21 September and bring together countries from around the world, donors and international development agencies, to jointly elevate the need to act on Early Warnings for All as an urgent climate adaptation measure

Early warning systems are effective adaptation measure that save lives, reduce losses and damages, and are cost-effective. Thanks to early warnings, the number of lives lost decreased almost three-fold in the past 50 years because of better weather forecasts and proactive and coordinated disaster management. Less than half of countries in the world have reported the existence of Multi-Hazard Early Warning Systems (MHEWS), with coverage particularly low in Africa, Least Developed Countries and Small Island Developing States.
